Documentation/usb/error-codes.txt包含usb错误号

Revised: 2004-Oct-21

This is the documentation of (hopefully) all possible error codes (and
their interpretation) that can be returned from usbcore.

Some of them are returned by the Host Controller Drivers (HCDs), which
device drivers only see through usbcore.  As a rule, all the HCDs should
behave the same except for transfer speed dependent behaviors and the
way certain faults are reported.


**************************************************************************
*                   Error codes returned by usb_submit_urb               *
**************************************************************************

Non-USB-specific:

0        URB submission went fine

-ENOMEM        no memory for allocation of internal structures   

USB-specific:

-ENODEV        specified USB-device or bus doesn't exist

-ENOENT        specified interface or endpoint does not exist or
        is not enabled

-ENXIO        host controller driver does not support queuing of this type
        of urb.  (treat as a host controller bug.)

-EINVAL        a) Invalid transfer type specified (or not supported)
        b) Invalid or unsupported periodic transfer interval
        c) ISO: attempted to change transfer interval
        d) ISO: number_of_packets is < 0
        e) various other cases

-EAGAIN        a) specified ISO start frame too early
        b) (using ISO-ASAP) too much scheduled for the future
           wait some time and try again.

-EFBIG        Host controller driver can't schedule that many ISO frames.

-EPIPE        Specified endpoint is stalled.  For non-control endpoints,
        reset this status with usb_clear_halt().

-EMSGSIZE    (a) endpoint maxpacket size is zero; it is not usable
            in the current interface altsetting.
        (b) ISO packet is larger than the endpoint maxpacket.
        (c) requested data transfer length is invalid: negative
            or too large for the host controller.

-ENOSPC        This request would overcommit the usb bandwidth reserved
        for periodic transfers (interrupt, isochronous).

-ESHUTDOWN    The device or host controller has been disabled due to some
        problem that could not be worked around.

-EPERM        Submission failed because urb->reject was set.

-EHOSTUNREACH    URB was rejected because the device is suspended.


**************************************************************************
*                   Error codes returned by in urb->status               *
*                   or in iso_frame_desc[n].status (for ISO)             *
**************************************************************************

USB device drivers may only test urb status values in completion handlers.
This is because otherwise there would be a race between HCDs updating
these values on one CPU, and device drivers testing them on another CPU.

A transfer's actual_length may be positive even when an error has been
reported.  That's because transfers often involve several packets, so that
one or more packets could finish before an error stops further endpoint I/O.


0            Transfer completed successfully

-ENOENT            URB was synchronously unlinked by usb_unlink_urb

-EINPROGRESS        URB still pending, no results yet
            (That is, if drivers see this it's a bug.)

-EPROTO (*, **)        a) bitstuff error
            b) no response packet received within the
               prescribed bus turn-around time
            c) unknown USB error

-EILSEQ (*, **)        a) CRC mismatch
            b) no response packet received within the
               prescribed bus turn-around time
            c) unknown USB error

            Note that often the controller hardware does not
            distinguish among cases a), b), and c), so a
            driver cannot tell whether there was a protocol
            error, a failure to respond (often caused by
            device disconnect), or some other fault.

-ETIME (**)        No response packet received within the prescribed
            bus turn-around time.  This error may instead be
            reported as -EPROTO or -EILSEQ.

-ETIMEDOUT        Synchronous USB message functions use this code
            to indicate timeout expired before the transfer
            completed, and no other error was reported by HC.

-EPIPE (**)        Endpoint stalled.  For non-control endpoints,
            reset this status with usb_clear_halt().

-ECOMM            During an IN transfer, the host controller
            received data from an endpoint faster than it
            could be written to system memory

-ENOSR            During an OUT transfer, the host controller
            could not retrieve data from system memory fast
            enough to keep up with the USB data rate

-EOVERFLOW (*)        The amount of data returned by the endpoint was
            greater than either the max packet size of the
            endpoint or the remaining buffer size.  "Babble".

-EREMOTEIO        The data read from the endpoint did not fill the
            specified buffer, and URB_SHORT_NOT_OK was set in
            urb->transfer_flags.

-ENODEV            Device was removed.  Often preceded by a burst of
            other errors, since the hub driver doesn't detect
            device removal events immediately.

-EXDEV            ISO transfer only partially completed
            look at individual frame status for details

-EINVAL            ISO madness, if this happens: Log off and go home

-ECONNRESET        URB was asynchronously unlinked by usb_unlink_urb

-ESHUTDOWN        The device or host controller has been disabled due
            to some problem that could not be worked around,
            such as a physical disconnect.


(*) Error codes like -EPROTO, -EILSEQ and -EOVERFLOW normally indicate
hardware problems such as bad devices (including firmware) or cables.

(**) This is also one of several codes that different kinds of host
controller use to indicate a transfer has failed because of device
disconnect.  In the interval before the hub driver starts disconnect
processing, devices may receive such fault reports for every request.
